Application filed December ToaZZ wlw/m Muay concern: y

lie it known that I, Jeroen it. KUHN, a citi zen oiI the' United States,\y residing at New `lastle, in the county of Lawrence and State of Pennsylvania, have invented a new and useful Improvement in condensing Apparatus, ot which the `following is a specilieation. This invention has reference tof condens-` ing apparatus 'for cl'iilling materials, and while not eoniined to vany particular use, is intended more especially for chilling or condensing ammonia. i

In ordinary ammonia systems of refrigeration, there is provided a coil of pipe of suitable length perm-ittingtlhe down flow of ammonia for cooling. The ammonia is di.- reeted to the upper portion of the' coil ot pipe to flow down through the coil, and the amn'ionia is sirbj eeted to the :cooling action of numerous streams oft a Vcliiiling mediuan, such as water, permitted to gravitate over the arrimonia pipes `frein a high to a low point,'so that the temperature ot the ammonia is reduced by the effect of the chilling medium, as usual. y

The arrangement is such that the chilling medium is widely and evenly distributed, while they structure is such as to admit of ready attachment to the ammonia coils without in any manner disturbing the latter, and no change is necessary in installed ammonia coils. l

In accordance with this invention, provision is made 'for coupling a distributing device for the cooling water to a supply of water, having a detleetor or battle fastened on top ot theA water supply pipe, and the ydetleetoii' or baille has numerous vents bei tween partitions, with the vents opening` upwardly, so as to cause the water to impinge against upwardly approaching wallsV and escape from the baille by way of many apertures at the sides of the pipe on which the distributing battle is located and secured. The baffle is located over and above the ammonia coil to receive the cooling water by gravity, to flow down over the usual series of ammonia coils and so subject the coils to the cooling action of the gravitating water. The baille structure has end caps and intermediate plates to distribute and segregate the cooling water, so that its distribution is quite uniform and the cooling of the ammonia coils is correspondingly uniform. The invention will be best understood trom a considera-tion of the following de- 5, Y1921. semina. 520,079.

tailed description, .taken in conjunction with the accompanying drawing forming part of thisv speciiication, with the understanding, however, that the invention "is not confined to any strict conformity with the showing oiPv the drawing but .may be changed and modiiied, so long as such changes and modiiications marl( no material departure from the salient features of the invention, as eX- pressed in the appended claims.

in the drawing,

Figure l is an elevation of an ammonia or other coil, and distributing device for carrying `out the invention.

Figure 2 is a. longitudinal vertical section ot the structure .of Figure l.

Figure 3 is a cross section ot thev cooling or chilling structure of Figure l.

In the drawing, there is shown a .coil 1,- such as is usuallyused in connection with ammonia coils, although it may :be Vtalren as typical et other 'coils where chilling is to take place, and for simplicity of description, such coil will be hereinafter referred to as an ammonia coil, although the invention may be employed in connection with other substances than ammonia.

At opposite ends, and at intermediate points, it necessary, there are erected upon the coil l, posts 2, designed to support a pipe 3, usually Athough not necessarily, made up ot ten toot sections, having an intermediate coupling 4, and at the outer ends closed by caps 5. The coupling et may be in the form of a T coupling, to which communicates a supply pipe 6, whereby water, or some other cooling material, may. nd its way into the pipe 3, being diverted through the coupling l` toward each end of the pipe 3.

Through the top of the pipe 3, are numerous vents 7, of' appropriate size, to permit streams of water to flow therethrough. Resting on top of the pipe 3 is a tapering shield or crown S, rising to an appropriate height and covering the vents 7. The shield 8 tapers to a relatively sharp edge and is wide enough at the lower edge to rest upon and he supported by the pipe 3, in substantially tangential relation thereto on both sides of the pipe, while the lower or wider edge of the shield 8, is furnished with a longitudinal series oi notches 9, preferably though not necessarily oit' V form. The notches 9 are cut back into the walls ot the shield 8, so as to provide ready escape for water, which may enter the shield S, through the vents 7, and gravitate from the shield by Way of the notches 9. The shield forms what may be termed as a crowned duct for the Water.

In order to control the distribution of Water from the pipe 3 into and from the' shield 8, said shield 8 is closed at each end, and contains numerous lateral partitions 10, acting after the manner of battles, Whereby the Water entering t-he pipe 3 is caused tot rise against the tapering inner Walls of the shield 8, to be diverted toward the Wider or basic edges of the shield 8 and be caused to flow downwardly about the outer surface of the pipe 3, and through the notches 9, and from the surface of said pipe 3, to the coil pipes l at a lower level. To render the structure rigid, an appropriate number of straps ll, are soldered or otherwise joined to the shield 8 and also joined together about the pipe 8, by bolts l2 or otherwise, although it is quite feasible to connect the straps together in encircling relation to the pipe 3 and to the shield 8, by solder.

What is claimed is r- 1. A device for cooling condensing` coils, comprising a Water pipe adapted to be located above the coil, a hood in the shape of an inverted V adapted to rest With its lower edges upon the Water pipe, a series of clamping straps encircling the pipe and hood and clamping the same together,

'surface beneath the hood to direct streams of Water against the inclined sides of the hood and thence through the notches and about the Water pipe.

2. An attachment for cooling condensing coils, comprising a Water pipe adapted to be mounted on the coil and provided with a series of spaced perforations along its upper face, said pipe having closed ends and an intermediate supply pipe, and a detachable flared hood covering the upper side of the Water pipe and closed at its ends, a series of clamping straps encircling the pipe and hood and clamping the same together, said hood being provided With a longitudinal series of edge openings to provide escape for the Water about the exterior of the pipe, said hood being also provided with a plurality of transverse partitions t cause uniformity of distribution of the Water about the Water pipe and thence about the coil.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
